The vaccuum hose from the BOV goes to where. and how i have a t-25.... how do i set the wastegate to 8 psi?

 

connect the bov to an intake manifold source such as the fuel pressure regulator or a pressure fitting after the throttle body. u can use a plastic T fitting to splice into the lines if u need to.

the factory setting for the t25 turbo i've always heard to be 8psi but i guess you could just try this method if its not... http://zoogle.zapto.org/wastegate.jpg although i've never tried it.

hope i helped
